This invention relates in general to spools, and more part-mularlyt-o that type of spool which comprises a cylindrical tube or core .having'disks oiflanges secured to its ends between which upon the core lswound mate- "rial to be spooled.

One object of the invention is to provide a novel and improved device for securing the disk or flai'ige upon the end of the tube or core, whereby the disk may be easily and securely fastened to the core and firmly held against both lateral movement and rotation on the core.

Other objects are to provide a device of this character. comprising a plate having arms projecting from the outer periphery thereof and at'on-e side at an angle to the the tubeor 'core with the plate overlying the Outl-31(l8 0l the disk, said arms having proections on their outer sides, and a member in engagement with and'slidable between the arms longitudinally thereof awayfrom the piate to press the arms into contact with the inner walls of the tube or core and cause said projections to penetrate said provide such a'deviceso constructed. that said member may be actuated from one end of'the tube or core and shall remain within the tube to positivelyhold the projections onthe arms in the tube; to provide seats on said a rms to recelve said member andlunit movement thereof in all directions; to provide a a novel and in'iproved construction and combination of such a fastening device, the disk, and the tube, whereby rotzdion of the disk relatively o'fthc tube shall beprevented; and to obtain other advantages and results as will be brrmght out by the following description.

inclusive, the reference vch'aracter 1 designates a cylindrical tube or core, usually made of paper or other fibrous material, and to the ends oti'which are secured disks. vor en d flanges 2. These disks 2 havecentral 0 m ings 3 of a diameter somewhat less than the internal diameterof the tube 1, and the edges of theopenii'ig 3 arenotched at l'to receive the arms oiithe fastening device about to be 7 described, j

This fastening device comprises a plate 5 formed ofsuitable material, preferably sheet metal, which has a plurality of arms 6 'pro-90 jecting from the outer periphery and at one side thereof at an angle to the plane of the plate. The outer side of each of these arms is "formed with one or more tooth-like projections 7. The distancebetween the opposite arms 6 at their juncture with the plate 5 is slightly greater than the interior diameter of the tube Land before the fastening device ismserted into thetube, the arms are pret- V crab-1y inclined inwardly toward each other as shownin Figure 3, so that they may be freely. slipped into the tube. A disk-like member 8 having a diameter somewhat less than the internal diameter of the. tube 1 is arranged betweenthe arms 6 so as to be slidable longitudinally thereof and in engage ment therewitl1,in the direction away from the plate 5 and toward the free ends of the arms.

For actuating the member 8, the plate 5 may be formedwith a central opening 9 through which may be inserted .a tool A which. has a reduced end portion B provided with a shoulder G at the inner end of the reduced end portion, and the member 8 may havea central opening 10 of a diameter somewhat greater than the reduced portion B but smaller than the Shoulder C, so that when the end portion B oif the tool is inserted through the opening 10, the member 8 may be pushed inwardly of the tube.

which pressure is eXerted on the tool to force the member 8 longitudinally of the arms 6, as shown in Figure 4. his action presses the'arms outwardly into contact with the inner walls of the tube, and eventually causes .1 the projection 7 topenetrate the tube, as

8 asit is slid toward the free ends of they arms, and to'snap inwardly against the side of the member 8 opposite the abutments 11 shown in Figure 1, so as to prevent the device from pulling out of the tube. J

j The free ends oi the arms are provided with abutments 11 to limit sliding movement of the member 8 toward the ends of the arms, and for preventing movement of the member 8 in the other direction, I may utilize a spring detent 12 in each arm which may be stamped upwardly from the arm. These dctents 12 are arranged to be depressed by the member after the member has reached said abutments. i

With this :onstruction, it will be observed that the end disk 2 maybe easily, quickly and firmly secured to the end of the tube 1 so as to beheld against movement relative to'the tube in all directions.

Rotation of the disk on the tube is prevented by engagement of overlie the outside of the disk 2.

the notches 4 with'the arms 6. 7 To prevent the plate 5 from being pushed inwardly through the opening 3, the plate'between extensions 13 to To reenforce the plate againstbending, the edge of the opening 9 may be former with a flange 14 which may be integral with the plate.

the. arms 6 is formed with arms much longer than would be "possible were the arms formed at the inner periphery of the plate; and the armsso located with respect to the plate, cooperate with the plate" to greatly reinforce the outer endof the tube 1. If the arms ,were at the inner pe-' riphery of' the plate, only. the inherentstrength of the arms could be relied upon to reinforce. the end of the tube. Furthermore, the disk-like member 8 in cooperation with the arms effectually reinforces the tube at an intermediate point inthe lengthof the tube.

A modification of the invention is shown. in Figures 7 and 8. The construction of this modifiedform is in general the same as that shown in Figures 1 to 6, inclusive, the difii'erence being that the spring tongues 12 are omitted, and the sides of the arms 15 are. formed with inturned flanges 16 which radually increase in width from the plate toward the free ends of the arms. Adjacent the free ends oi. the arms the flanges 16 are formedwith seats 17 to receive themember 8. The flanges reent'orce the arms, and. also e11 able the arms to'be forced outwardly'at their free ends a greater distance than j at their other ends, so that asecure attachment of the fastener device in the tube may be obtained without damaging the end of the tube.

This fastening device isused and operated in substantially the same manner as the device shown in Figures 1 to 6, inclusive, the

member 8. sliding', along the edges of the flanges 16 so as to press the arms" 1:} outwardly into contact with'the wallsof the tube until the member 8 reaches the seats .17, whereupon the member snaps into said seats andis held against further movement with suitable projections 19 corresponding to form width throughout their length.

VVith this form ofthe invention, the memin all directions. lhe arms 15, are provided the projections 7 torsecuring, thefastening.

her 8 is'slid along the edges of the flanges 20, constantly pressing thearms 22 outwardly in I contact with the inner wall of the tube, until. the member reaches the portions 21 of the flanges, whereupon outward 'movement of the arms stops. Thisconstruction has advantages over the construction shown in F ig-f.

ures 7 and 8, in that there is-notendency of the arms 22 to. spring inwardlyafter-the member 8 has reached the seats 21', as is the case when the member 8 reaches-the seats 17. Such inward swinging of the arms after they have been pressed outwardly to the limit, tends to withdraw the projections 19 from the tube and lnduce some looseness, although not enough looseness to interfere with the secure attachment ofthe fastening device to the tube. l I

For limiting movement of the member 8 toward the free ends'of the arms 22, abut-' ments 23 may be formed at the outer ends of the portions 21 of the flang e,.and to prevent movement of the member 8 in the'opposite direction, a spring detent 24like the. detent"12,

may be provided in each arm 22 to engage the side of the member S'opposite the abutments 23. As the member 8 slidestoward the free ends of the arms 22, it depresses the detents 24 and slides thereover, and after the member 8 has passed the detents, they snap cause saidprojeetions to penetrate said tube,

outwardly, as shown in Figure 9;

While I have shown my invention as embodied in several different forms and in dif ferent details of eonstructiomiit should be understood that this is primarily for thepurpose of illustrating the principles of the 1nvention, and that the details of construction may befurther modified or changed by those skilled in the art without departing from the spirit or scope of the invention.
